went on a bike ride this morning, after 5 minutes it stopped tracking my heart rate and didn't even track the time, which is a first! Other bike rides and runs it never makes it all the way and flat lines loads of times during the exercise. I have spent £300 on a heart rate monitor that doesn't work and Samsung just tell me to take it to the repair shop! Really do I think they will have a clue what to do!

I think it's software, I use the Workout Trainer app on my watch and that tracks heartrate perfectly. If I use the on board workout tracking it's awful. The watch is absolutely capable of tracking heartrate but it seems that Samsung's software responsible for this is totally useless. They need to look at third party compatible aps which track workouts and heartrate and the software used.

My S3 has identical problems as regards Heart Rate. Samsung suggested a factory reset which did nothing and after further communications said someone would contact me ASAP which also never happened.

Meantime I reduced the Apps and notifications and kept strictly what I needed without result. Then as a wild card I shaved the area directly beneath the watch and I am NOT a hairy guy. It now works and records without issue. So tightening straps to silly levels might help but shaving a small area woirked for me. Hopefully Samsung will resolve the issue as all my other sports watches never had this issue! (but their straps fell apart) Good luck

I'm terribly disappointed with my Galaxy Watch. I'm using it since day one (pre-order on-line).

I have A LOT of problems with heart rate and stress trackers. Almost all the time, I don't see a proper result on my screen, all I see is a "Measuring..." message. The watch trying and trying to detect HR and stress. How can I ***TRUST*** this? Specially during exercises? Even during exercises, the trackers failure many times.

The watch is correctly placed. The sensors (the green light) are clean. The trackers are set to measure HR and stress continuously. I rarely sweat. But the problem persists, no matter if I'm on an exercise or very calm on my couch.

Before this Galaxy Watch, I had a HUAWEI WATCH 2. This kind of problem NEVER ocurred. Always PERFECT.

Now I search Google and find lots of people complaining about the same thing about the Galaxy Watch, month after month. Where's the fix? What a shame, Samsung.
